About CV and KV Calculations

CV Formula (US Customary)

CV = Q 脳 鈭?G / 螖P)
  • CV = Flow coefficient (gpm of water with 1 psi pressure drop)
  • Q = Flow rate (gpm)
  • G = Specific gravity (relative to water at 60掳F)
  • 螖P = Pressure drop (P1 - P2) in psi

KV Formula (Metric)

KV = Q 脳 鈭?蟻 / 螖P)
  • KV = Flow coefficient (m鲁/h of water with 1 bar pressure drop)
  • Q = Flow rate (m鲁/h)
  • 蟻 = Density (relative to water at 15掳C)
  • 螖P = Pressure drop (P1 - P2) in bar
